Will do tomorrow

yes, sorry it's supposed to be 240 not 250. I am not sure what its phase is

I have solved it (: Homework Statement Ir=Impedance of a resistor = 330 Ic=Impedance of a capacitor=318 V= Sinusoidal Voltage = 240 V (RMS) is applied across the series combination. calculate the resulting current. Homework Equations Not sure The Attempt at a Solution I am really not sure how...

I think the answer given to me was incorrect for that one, i did a similar question and got the right answer for it ;D I was writing down another equation in respect to the manometer so i can cancel stuff around

Homework Statement Question: http://i.imgur.com/aoXUDP1.png Homework Equations Q=v1A1=v2A2 Bernoullis Equation P=P0 + ρgh The Attempt at a Solution I have got an answer of 3.55*10^-3 m^3 /s. The answer i have been told is 1.29 x 10-3 m3s-1. I am not sure if i am wrong or the answer...

I got it. Thank you for the help and yes you were right, 0.012 is the actual value, turns out i just heard him wrong. sorry for the inconvenience

Assuming I am only expected to calculate the flow rate and let's imagine that 0.012m^3 and Cd doesn't exist. How would I do it? I got as far as finding the equation so that I have the variables P2 and v2 which I don't know and am really stuck on that part. I did the following, equation...

I am really confused now, my professor said that was the theoretical flow rate

Theoretical flow rate is already given 0.012 m^3s^-1. I need to calculate the actual flow rate

How does calculating the flow velocity at the inlet and throat help in terms of Q as Q is only theoretical and I am trying to work out practical?

Homework Statement A Venturi meter is constructed with an inlet diameterof 100 mm and a throat diameter of 40 mm. The meter must be calibrated prior to leaving the factory. The meter is installed in a 100 mm diameter water main with a...

ye I was just being stupid, ty for the help

f(q)=i ?so integral of 3A which is (3t^2)/2 ?

Homework Statement A dc current of 3 A flows through an initially discharged capacitor. After 2 micro s what is the electrical charge on the capacitor? Homework Equations q(t)= integral i(t) dt between t=0 and t The Attempt at a Solution (3t^2)/2=6x10^-12 C. Is this right?
